Spatially Resolved Characterization of the Local Superconducting Properties of Compositional Gradient REBCO Films

We have succeeded in developing a high-resolution and high-throughput measurement method for local sheet current density (J<inf>s</inf>) and critical temperature (T<inf>c</inf>) in a thin film sample prepared by Transient Liquid-Assisted Growth using Chemical Solution Deposit...
